js和native交互 互相调用

必须这样写，如果用vue可以在app.vue里面写，先把WebViewJavascriptBridge弄到window下面

function setupWebViewJavascriptBridge(callback) {

        if ((window as any).WebViewJavascriptBridge) { return callback((window as any).WebViewJavascriptBridge); }

        if ((window as any).WVJBCallbacks) { return (window as any).WVJBCallbacks.push(callback); }

        (window as any).WVJBCallbacks = [callback];

        var WVJBIframe = document.createElement('iframe');                

        WVJBIframe.style.display = 'none';

        WVJBIframe.src = 'https://__bridge_loaded__';

        document.documentElement.appendChild(WVJBIframe);

        setTimeout(function () { document.documentElement.removeChild(WVJBIframe) }, 0)

}

 setupWebViewJavascriptBridge(function (bridge) {

        // window.JSBridge = bridge;

 })

具体用的时候

js调用native（原生的，ios或者安卓端）

(window as any).WebViewJavascriptBridge?.callHandler(native端的方法名, {参数}, (返回值) => {})

 

native调用js的

(window as any).WebViewJavascriptBridge?.registerHandler(native端的方法名, (返回值) => {})
